The location dictated that I use that much concrete. As Greg said its all about the mass.

I am not sure but if you can further extend the concrete and use the concrete as the pier then vibration issue will be a lot less compared to a metal pier. Some of the equipment driving the mount can be fixed to the concrete as well.

I am going to place a pier onto the concrete. It will be a Software Bisque pier. It has a tube diameter of 254mm and base and top plate of 12mm. The mounting holes are pre drilled.
I thought about using concrete as a pier but decided against it. I am sure I read on another thread that a concrete pier will have more flex than a metal one. ( Don't quote me on this, I might have it backwards). I am sure there would be someone here that can clarify this.
As far as vibrations go, filling the pier with some sort of dampening material might work. I am not sure if this needs to be done or not. I will have to wait till I get the mount and the telescope setup and trial it.
